According to the Nikkei report, which is written in Japanese and was interpreted with the help of Google Translate, the currently available shells have a low build quality — the home button doesn’t fit perfectly, there are rough edges, and there are unpolished burr marks. So it’s unlikely that these shells are actual Apple parts. But Nikkei’s sources say the final iPhone 6 will look very close to the available mockups: for instance, they say the Apple logo will in fact be cut out, which matches what we’ve seen from other leaked parts. The final iPhone will also be similarly thin with an iPod touch-like design, but will likely feature a different antenna design on the back than the mockups currently show.
